Design, Testing, and Simulation of a Low-Cost, Light-Weight, Low-g IMU for the Navigation of an Indoor Blimp
(2008-09-09)
In this thesis we develop an IMU for the purpose of navigating an autonomous indoor blimp. Due to the unique system properties of an indoor blimp, the developed IMU is light-weight and is capable of measuring slow rotational ...
Cold Cathodes for Applications in Poor Vacuum and Low Pressure Gas Environments: Carbon Nanotubes Versus Zinc Oxide Nanoneedles
(2008-09-09)
Effects of gas pressure on the electron field emission (FE) properties of zinc oxide (ZnO) nanoneedles and carbon nanotubes (CNTs) were investigated. The FE properties for ZnO nanoneedles almost fully recovered after being ...
Efforts Towards the Design and Development of an Electromagnetic Induction Sensor Optimized for Detection and Discrimination of Unexploded Ordnance
(2008-09-09)
This thesis provides a detailed description of efforts towards the development of a time domain electromagnetic induction (EMI) system optimized for detection and discrimination of Unexploded Ordnance (UXO). A time domain ...
Practically Realizing Random Access Scan
(2008-09-09)
The number of clock cycles in a serial scan (SS) test is often prohibitive as the number of flip-flops (FF) increases. Besides, scan-in and scan-out sequences result in unwanted circuit activity. This increases the test ...
Perfomance Analysis of 802.11b Networks
(2008-09-09)
Wireless local area networks (WLANs), especially those incorporating the 802.11b standard, have experienced rapid evolution and unprecedented widespread deployment during the past few years. Increasing research led to the ...
